RAIL-JOINT.

Application filed October 24, 1914, Serial No. 868,425. Renewed April 16, 1917. Serial No. 162,525.

To all whom t may concern.'

Be it known that I, ALBERT GIMPEL, a citizen of the United States, residing at Mountain View, in the county of Howell and State of Missouri, have invented certain new and useful Improvements in Rail- Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to rail joints.

My object is to supply a rail for use on railway and tramway tracks that can be used without the necessity of connecting the joints by means of iish plates, angle plates, or similar' means.

In the drawings herewith which are made a part 0f this application,-

Figure l is a side elevation ends embodying my invention,

Fig. 2 is a plan view of the flange of two rail ends,

Figs. 3 and 4 show a side elevation of two rail ends, the ends being separated.

Fig. 5 is a perspective view of a rail end showing the form of the slot and groove therein, and

Fig. 6 is a perspective view of the end showing the tenon thereon.

My invention contemplates an adaptation of the ordinary steel rail having a ball 1, a web 2 and a iiange or base 3, and litting it with the slot 4 and groove 5 in one end and the tenon 6 at the other end.

When forming the slot 4, the flange is cut along each side of the web as at 7 a sufficient distance to form a firm bearing for the joint on the tie, beginning at the end of the rail and carrying the cut inwardly toward the opposite end the required distance. A perpendicular cut 8 is made at the end of the iirst named cut, and at a right angle thereto. The cut 8 is carried upwardly through the flange and an additional distance equal to the thickness of the flange. A longitudinal cut 9 is then made from the cut 8 to the end of the rail, the plane of the cut 9 being parallel with the planeof the flange or base of the rail.

A groove 5 having the shape of an inverted V is formed in the remaining portion of two rail of the web at the end of the rail, and eX- tends longitudinally along the under side thereof the full length of the slot 4. The converging point of the two sides of the groove is positioned centrally of the perpendicular side lines of the web, the diverging lines of the groove intersecting the said side lines of the web where the side lines and the base line of the cut portion of the web meet.

.A tenon 6 isA formed upon the opposite end of the rail by cutting away the flange on either side of the web and also the ball and a part of the web above the said tenon, suilicient of the lower part of the web remaining attached to the end of the rail to form a tenon of the exact size and shape to snugly fit the slot 4 and the groove 5, the upper surface of the said tenon being cut away on each side to form a wedge shaped edge l0 that will lit in the groove 5 of an abutting rail when the rails are laid in a line and the ends thereof are joined in forming a track. The sloping sides of the wedge shaped edge of the tenon being designed to readily shed the dust and grit that naturally settles on a flat surface.

I When laying a track with rails having my joint, it is only necessary to spike the rails to the ties using the precaution to space the ties at a proper distance to bring a tie directly under the joint to form a support therefor. The tenon entering the slot prevents any lateral movement of the rails at the joints and performs the function of fish plates or angle bars and also forms a more rigid joint making a practically continuous rail.

Having now fully described my invention, what I claim as new and desire to secure by Letters-Patent, is :I

A rail joint comprising a rail section having an extended tenon at one end, the upper face of said tenon being inclined downwardly in opposite directions from a central line, and a cooperating rail section having at one end in its base a longitudinally extended slot, the web of the rail being cut away upon each side corresponding to said slot leaving a depending portion of the web with its under face formed with a groove the walls of which are oppositely inclined from the center outward to correspond with improved 5 Wedge shaped groove of s a-d' epending per vVVT''nesses:

the inclined Walls ofV the upper face of said name to this Speccaton in the presence of;

tenen,vr said tenen being received in the slot' 'two subscribing Witnesses. Y of thebase ofy the rail Section and the Wed'oe Y shaped face of the tenen received 'n tle ALBERT GIMPEL' tion. e y y W. T. CQGHILL,

VIn testimony whereof I- have signed my HASKINSHOBSON.
